The windshield Wipers-or wiping eleinents are operated bye motor 16 of suitable charactor for oscillating the Wipers 'ljut which forms'rio part of this invention. It can be supported, however, in opefative p osition by the mounting which forms part of the in venti on. As shown the "11101301" has "a pair of brackets 16js'ptic'e'd apart thereon, these be iiigdflgieritarhl U-sh'epe 'as shown in Figure 4 so that one side of the brz 'okets will fit against 'th'efinner edge of the ledge 12' :I'i d the brackets termimite in flanges 16 which lie on th'e fit'o p surface 'of the ledge 12'. Thus the liraql tets without any fastening except the "seoureinent of the motor "shafths pres e'ntly described serve 'to hold the motor in operating position.

The motor 0 "driving shaft 17 extends through sleeve 18 attached to the motor and passing through a tube lSWliic'h is a part of the windshield structure; being attached 'to the ledge 12. The outer end of the sleeve 1 8? projects through the slhsh 12 and :1 Corresponding hqle iii the body 10.

single act of positioning the parts and then tightening the nut serves to fasten the whole apparatus in place, but if desired another screw or bolt can be passed through the parts and 12 thus making an absolutely rigid and permanent support.

The shaft 17' of the motor projects f 01- ward a sufficient distance to carry the wiplng element 20 which can be ofany. preferred kind and which operates in the customary way by oscillating against the wind shield glass.

Secured to the shaft 17 in close abutment with the sleeve 18 is a gear 21 which is oscillated by the movement of the motor and its shaft and which engages and reciproeates a toothed rack 22 which extends lengthwise of the body 10 and beneath the projecting hood or flange 11.

At the motor end of the device the rack 12 is guided in a channel member 23 Which is fastened to the under side of the hood or flange 11 andcan be conveniently and rigidly secured by spot. weldin The rack 22 extends beneath and parallel with the hood or flange 11 which to prevent vibration of the rack may be bent downwards slightly asat 24 so as to form a bearing against which the rack lightly rides.

At an appropriate distance from the wiping element 20 is a second wiping element 21 and themeans for operating thesefrom the rack 22 is provided for as follows.

At this point a second channel 23 is provided which guides the rack 22 which is deeper so as to afford a means of guiding the second operating gear 21, one side of the channel member 23 being also made long enough to form a support 23", for the shaft of the wiping element 21'.

A further bearing is also provided for this shaft 25 by simply punching in the metal of the body 10 at this point as illustrated at 26 in Figure Thus a firm bearing is made for the shaft 25 and at the same time a guide for the operating gear 21 and the rack 22.

Near the end portion of the support which is farthest from the motor the body 10 is provided with a clamping member 27 which is on the top of the tlange or hood l1 and which is shaped to fit the top edge of the sash 12.

On the lower part of the body 10 and preferably in vertical alignment with the member 27 is an L shaped bracket 28. A second clamping member 29 aligning with the parts 27 and 28 is shaped to fit the lower edge of the sash 12 and has its outer end preferably This n1ember29 receives a screw bolt 32, or the like which is threaded in the part 28 and thus if the clamping members 27 and 29 are placed respectively on the upper andlower edges of the sash 12 and the bolt 32 turned'home. the parts will be securely clamped. The hole 29 through the part 29 is large enough to permit the said part 29 to be adjusted in and out so that it may be nicely seated on the lower edge of the sash 12. The second end of the mounting is rigidly fastened to the sash and the whole apparatus is secured with the necessity of making but one hole through the sash 12 that is to receive the part 18 as already described, though if it is desired to put a hole through the body 10 and sash 12 near the second end of the body, this can be done to make it even more rigid.

From the foregoing description it will be seen that the mounting for the tandem wiping elements, their operating mechanism and even the motor is of a very simple, neat, strong and substantial character, so that the whole can be assembled for shipment and then easily applied by any person of ordinary intelligence to the sash of the Wind shield.

The structure shown and described is eculiarly adapted for driving a tandem Wind shield wiper but it will be seen that if desired the second wiping element can be dispensed with and that the means disclosed especially as illustrated in Figure 4 for fastening and driving the shaft and motor to the sash in applicable for use in driving a single wiping element and affords a convenient, simple and substantial means of mounting such a mechanism.
